Specification of Letters Patent.

Patented April 20, 1909;

Application filed November 9, 1907. Serial No. 401,507.

To all whom it may concern:

Be it known that I, RICHARD S. BROOKS, a citizen of the United States,residing at Bonner Springs, in the county of l Vyandotte, State ofKansas, have invented certain new and useful Improvements in Gates; andI do hereby declare the following to be a full, clear, and exact descrition of the invention, such as will enable ot iers skilled in the art towhich it appertains to make and use the same.

This invention relates to gates and more particularly to that classwhich are designed to be 0 ened by the passage of the wheels of a vehice over a trip and the primary object of the'invention is to provide agate of this class which will be easy to 0 erate and simple in itsconstruction, its simp icity of construction adapting it for use in allclimates.

More specifically stated, the gate is of that type which are swung fromopen to closed position in a vertical plane and which are maintainedthroughout their movement, in horizontal position, and I have providedmeans whereby the gate may be opened upon the a proach of a vehicle andclosed after the vehic e has passed, and also means for slackening thespeed of movement of the gate toward either limit of its movement. Ihave found that one disadvantage apparent in gates of this type lies inthe fact that no means is provide for holding the gate against movementin a manner similar to the ordinary swinging gate and with the object inview of provi ing as far as possible a perfect construction of gate ofthis class I have conceived the idea of providing means whereby suchmovement of the gate will be positively prevented so that the stockcannot injure the gate by moving it out of proper alinement.

In connection with my gate I have further provided power transmittingmeans of such character as to permit of the passage of the rear wheelsof a vehicle after one or the other of the trips has been operated byone of the front wheels thereof and have also so constructed the powertransmitting mechanism that the gate may be built or set upon the ridgeof a hill, in a hollow, or upon uneven ground of any characterwhatsoever without any loss of the efliciency of the said mechanism.

In the accompanying drawings, Figure 1 is a side elevation of the gate,the same being in closed position, Fig. 2 is a similar view oftheopposite side, the gate being in open position, Fig. 3 is a top planview of the gate in closed position, Fig. 4 is an end view thereof inopen position, Fig. 5 is a detail vertical sectional view taken to oneside of one of the bearings for one of the trips and showing in fulllines the relative osition of the parts when the gate is closed and indotted lines their relative position when the gate is open Fig. 6 is avertical sectional View through one of the gate posts and thecorresponding end of the gate showing-the means for preventing lateralmovement of the gate, Fig. '7 is a detail view of one of the universaljoints for the power transmitting shaft.

In the drawings, the gate is shown as working between a pair ofspaced'parallel upright posts 10 and a post 11, the posts 10 beinglocated to one side of the road-way and the post 11 to the other sidethereof, A block 12 is set into the road-bed directly inwardly of thepost 11 and a similar block 13 is set into the road-bed inwardly-of thetwo posts 10 and in a plane intermediate the same. Similar blocks 14 areset into the ground to that side of the road to which the gate is to beswung to open position and the function of these four blocks willpresently be fully explained.

Journaled in suitable bearings 15 upon the posts 10 is a shaft 16 andrigidly connected to this shaft by means of clips 17, is a pair of bars18 which extend in spaced parallel relation with respect to each other.A rock shaft 19 is journaled in suitable bearings 20 which are fixedupon the sides of the post 10 opposite to the bearings 15 and rigidlyconnected by means of clips 21 to this rock shaft is a pair of spacedparallel bars 22. The gate proper may be of any desired constructionalthough it is here shown as consisting of end and intermediate uprights23 and horizontal bars 24. The upper ends of the arms 18 are pivotallyconnected as at 25 to one of the upper horizontal bars 24 of the gateand to one side of the intermediate upright 23, the arms '22 beingconnected, also pivotally, at their upper ends to the said bar 24 asindicated at 26 but at the other side of the intermediate upright 23.The points of pivotal connection of the bars 18 and 22 are spaced aparta distance equal to the distance between the shaft 16 and the rock shaft19 and it will thus be seen that not only are the bars of each pair heldin parallel relation, but that the two pairs of bars are at all timesheld in parallelrelation with respect to each other and it will furtherbe understood that rotation of the shaft 16 will result in a verticalswinging movement of the bars 18 and 22 and a sindlar leve ment of thegate proper, the gate be maintained by the nanner of connecting the bars18 and 22 therewith at all times in horizontal position. As the gate isswun g, in a manner which will be presently described, from one positionto another, it seats, when closed, upon the i;-lOC-l-IS 12 and 13 at itsrespective ends and wlien open upon the blocns 14-. In order that thegate y be swung stated, I have provided suitable trips and powertransmission niechanis n connectin the trips and the shaft 16 wherebythe she may be rotated upon actuation of the trips and this hanisin willnow be (lescribed Suitable bloclrs 27 are set into the road-bed one toeach side of the gate and upon each of these blocks is lined a bearingJournaled in each of these bearings is shaft 29, this shaft being inalineznent with the shaft 16 and Xed upon that end of each shaft 29which is directed toward the shaft 16 is a sleeve 30 provided with ayoke portion 31, there being a similar sleeve 32, having a yoke 33,fixed upon each end of the shaft 16. The arins of each of these yokeportions are formed in their ends with openings 3 and the arms of theyokes upon the shaft 16 are disposed at riglrt angles to the arms of theyokes upon the sl'ia'fts 29. fr plate is provided with four studs whichare engaged at their ends in the openings in the two yokes at each sideof the gate and serve to connect the said yolies a manner substantiallylike a universal joi t it being understood that by this construction theshafts 29 may be disposed at an angle or inclination to the shaft 16without the sillciency of the device icing destroyed.

Fixed upon the outer end of each of the shafts is a bevel gear 36 andmeshing with this bevel gear is a similar gear 37 which is looselycarried at the end of a rocking trip 38, it being understood that two ofthese rocking trips are employed one to each side of the gate. Each ofthe rocking trips is substantially U-shaped in form and has itsconnecting portion indicated by the numeral 39 and its spaced portions40 formed with right angularly extended journals 41 which are engaged insuitable bearings 42 fixed upon bloclrs e3 set into the road-bed. It isupon one of these journals 41 of each of the rocking trips that thegears 37 are supported and these gears, as stated, are loose upon thetrips. however, in order that tae rocking of the trips may rotate thegears, the sleeve of each gear is cut away substantially to the extentof a quarter circle as is indicated at 44: and working in this cut awayportion is a stud 45 formed upon the said journal of the trip. Theoperation of these trips will presently be fully explained. Coiledaround the above mentioned journal of each rocking trip is a spring 46which is connected at one of its ends to the adjacent bearing and hasits other end extended upwardly and secured to the adjacent connectingportion of the trip, it being understood that these springs serve tohold the trips normally in ver ical or operative position.

Fron the foregoing description of inyinvention it will be understoodthat the gate being closed, depression of either of the trips in adirection toward the gate will serve to swing it to open position, thisdepression of the trip being caused by one of th'e 'front wheels of thevehicle traveling along the road and that after the gate has been'soswung, either of the trips may be depressed in a direction toward thegate but without any result being produced. lowever, after the vehiclelas passed the gate, the'front wheel of the vehicle will strike thetripat the other side of the gate and depress it in a 'di-' rection awayfrom the gate. This will result in its being swung to closed positionand after the closing trip has been so operated to close the gate by thefront wheels of the vehicle, the rear wheels may pass thereover with outproducing any effect.

In order to permit of ready operation of the gate and to reduce thepower necessary to its operation, an expansible spring 47 is connectedat its upper end, permanently, to one of the posts 10 adjacent the upperend thereof and at its lower end, to an eye bolt 48 which is engagedthrough the adjacent one of the bars 22 this engagement being hadthrough one of a plurality of openings 49 formed in the said bar, itbeing understood that by the provision of this plurality of openings,the tension of the spring may be adjusted. The tendency of this springis to norinally raise the gate, this tendency being overcome to aconsiderable degree by the weight of the gate. It will further beun'l'erstood that the tendency of this spring to raise the gate willallow the gate to drop slowly and evenly to either extreme of its limitsof movement, jarbeing in this manner obviated.

The means, heretofore mentioned, for the purpose of preventin movementof the gate in a manner ascribed to the ordinary swinging gate, consistsof a pair of wooden lugs50 which are fixed between the outer pair of enduprights 23 and which are designed to seat, when the gate is closed, inrecesses 51 formed in the opposing face of the post 11, these re cessesbeing gradually deepened downwardly or in other words having their rearwalls'inclined or cut at an angle as is indicated by the nurneral 52. Itis also preferable to broaden these recesses at their upper ends andform them at and adjacent their lower ends, where they are deepest, ofawidth equal to the thickness of the lugs 50. It will with one of thearms of the invertedU-shaped be understood from the foregoing that whenthese lugs are seated in the recesses, the gate will be prevented frommoving in the manner of a swinging gate as stated above.

To return to the trips and the gears carried thereby, it might be statedthat to more clearly define the structure, the gears carried by thejournals of the trips operate only when the trips are moved to bring thestuds to bear against the ends of the cut away portions of the gears,the trips having free move ment in the other direction.

What is claimed, is

1. A device of the class described com prising a vertically movablegate, a shaft mounted for oscillation to move said gate, trips includingeach an inverted U-shape portion, gears carried by the shafts and byeach of the trips whereby the shafts may be oscillated upon operation ofthe trips, bearings in which the trips are mounted, a spring engagedaround each of the trips, the said s ring being connected at one of itsends to t e bearings and engaged at its other end portion of the trip,the gears upon the trips having a limited rotary movement thereupon, thesprings serving to return the trips to raised position after actuation.

2. A device of the class described comprisin a pair of uprights,parallel shafts journaded upon the uprights, arms secured at their lowerends to the shafts, a gate, the said arms being secured at their upperends to the gate in parallel relation throughout their extent, meanswhereby one of said shafts may be rotated, a spring connected to one ofthe uprights, one of the arms being formed with a plurality of openings,and the spring being provided at its opposite end with an elementinsertible in said openings interchangeably whereby the tension of saidspring may be varied.

In testimony whereof, I affix my signature, in presence of twowitnesses.
